GUN-MOUNT.

"State of New York, have invented certain new and useful Improvements in Gun- Mo'unts, of which the'following'is a specificatiein g g The ebjeot of this invention is to provide an improved form of mount for rapid fire several of "which are mounted in a battery for simultaneous o eration "with a single control therefor.

. Another 'ebject ot the invention is't'o. provide for mechani'cal oscillation of the gun barrels collectively throu h a slight are and a manual swinging of the gun barrels up or down, or t'otheright or left, or a com- ,binationof these, as be desired.

These and other objects of the invention will be illustrated in the drawings and described in the specification.

In the drawings, like reference numerals indicate like parts. y I In the drawings; reference numeral 1 indicates the pedestal on whichthe cradle and gun barrels are mounted, on which are provided the two uprights 2 and At the top are provided the bearings 4, from which are swung the side plates "5 forming part of the cradle. These side plates are provided with the bearings 6 near the top thereof and are connected at the bottom by a plate 7 fas the screws 8, 8, 8. Mounted in the bearings 6 'arefthep'lates 9 which are fastened together and make a clamp between which are held the gun barrels. These plates are two in number and are shown in rear elevation in Fig. 4 and in side elevation in Figs. 1 and 5., These plates are provided with a bearing 10 with which engages the pin 11 that extends between the bearings 6, 6 in the plates v i The breech ofthe gun barrel is indicated at '12, 12,'the barrels themselves being indicated at 13. The forward part or the barrels pass through openings in the-plate 14. On the barrels are placed the flanged side or the plate 14, the flanges bearing against thepl ate and the sleeves engaging with the barrels. The sleeves are provided with theset screws 16 by which they are clamped in place on'the gun barrels on opposite sides oflthe plate 14, fixing the position of the plate '14 with relation thereto. 4 V 0 On the bottom of the cradle is a bracket 17 on which is provided a motor 18, 11 the shaft of which isprovided a crank connected by alink 20 to the plate 14. Therotation of the armature of the motor causes the plate 14 to move up and wn api y; making about sixty complete oscillations a minute.

the gun mount in line with the middle" barrel of the battery, the divergence being sufficient to give a spread to the bullets fired simultaneously from the barrels of about '1 IO 18 ft. at adistance of a thousand feet from the muzzles of the guns, the gun barrels being placed in the frame about 12 inches between centers or just sufficiently spaced apart to giveugood clearance between the handles of consecutive gun barrels.

-The gun barrels are fired automatically and simultaneously in any desired-way. The mechanism by which this can be done may be of any of the well-known types and constitutes no part of my invention.

'As is indicated by the crank 19 and link 20, the gun barrels are oscillated through a very small arc, the gun and oscillating mechanism being designed so that each gun barrel will shoot five shots while the gun barrels are swinging upv and five shots while the gun barrels are swinging down, or any 1 other desired number. Ifthe outside bullets 7 from the second barrel.

of the first volley are 18' ft. apart at a thousand feet from the muzzles of the guns, the five bullets of the volley will then be spaced 4%; ft. between centers. The oscillation of the gun barrels will cause the next four bullets from each gun barrel to fill in this space of 4%- ft. or 54.- inches at intervals of about 11 inches at 1,000 ft. from the muzzle of the gun barrel, so that in five successive volleys, 25 bullets will be fired spread out over a width of about 22 ft., the bullets traversing the intervening space at approximate intervals of about 11 inches between centers. In this way the second bullet from the first barrel will pass about 11 inches below the first bullet of that barrel andv the third bullet from the first barrel will pass 22 inches below the first bullet, the fourth bullet will pass 33 inches below the first bullet, and the fifth bullet will pass d i'inches below the first bullet, or about 11 inches above the bullet of the first volley Thereafter, the gun barrels will swing back in the opposite direction until five volleys have been fired after which they will again swing in the first direction, repeating this operation indefinitely. 1

t The angle of oscillation must be substantially the same as'the angle of divergence between two adjacent gun barrels to secure this distribution of the shots. 1

It will also be understood that while the gun barrels are oscillated around the center 11 by the motor 18 mechanically, the gun bullets over considerable width will be secured, which will compensate to a considerable extent for the inaccuracy of the operator in aiming and will produce effective results.

In Fig. 12 I have. shown a pedestal 30 in which is mounted a cradle 31 in which .swingsa frame 32 in which are supported" the five gun barrels, the barrels being mounted thereln in a horizontal row in substantially the same manner as is shown in vertical arrangement in Fig. 1. The bar-" 7 rels are connected by'the bar 33 which is V, V

oscillated up and down by the link 34 driven by the crank '35 from the motor 36. The

frame 32 swings on the center 37 in the cradle 31, which in turn swings on the center 38 inthe pedestal 30. The cradle 31 turned to the right or left so that the opercan be moved manually to swing the guns up or down and the pedestal'3O can be ator can thereby'train the guns in any desired direction.

As shown in Fig. 13, the oscillation of the gun barrels is up and down whichlwill cause the bullets to be sprayed in five parallel columns instead of a'sin le continuous row. The angular mechanicahmovement of the barrels in'this case may be 'increasedfto secure desired variations in the distribution of the bullets. V p e A firing control is shown inFig. 1, which consistsof a bar 21 pivoted at 22, having a handle 23 on the bottom thereof. This bar is provided with pins 24 suitablyplaced for engagement with the triggers 25 as the bar swings rearwardly. A hand rest 26 is shown which may be grasped by the hand, one or more, fingers engaging the handle 23 by which the bar 21 may be swung backward into enga ement with the triggers. With the bar he d in firing position, uns will repeat automatically, any suitab e devicebeing used, if necessary, to secure the firing of the guns simultaneously.

I claim: a

1. A gun mount having a gun barrel.

mounted therein, means on saidmount for oscillating said gun barrel mechanically and independent of the operator through a small fixed are at a high rate of speed permitting a small number of shots to be fired at equal 1 intervals in quick succession in each oscillation, and .supplementalfmeans for oscillatlng said barreli'manually' and more slowly through a larger arc and independently of and simultaneously with the mechanical os-' cillation thereof.

2. A gun mount having a U-shaped pedese tal, a cradle mounted to swing in said pedestal, a frame having a gun barrel mounted to swing in said cradle, mechanism carried f on the cradle for mechanically oscillating the gun'barrel througha small are at a high rate of speed independent of the operator,

- permitting a small number of shots to be red at equal intervals in quick succession in each oscillation, said cradle mechanism and barrel being capable of swinging through a larger arc without interfering with the mechanical operation of the gun barrel.

3. A gun mount having a U-shaped pedestal, a cradle mounted to swing in said pedestal, said pedestal being mounted to turn with the cradle, a frame having a gun barrel mounted to swing in said cradle, mechanism carried on the cradle for mechanically oscillating the gun barrel through a small arc at a high rate of speed independent of the operator permitting a small number of shots to be fired at equal intervals in quick succession in each oscillation, said cradle mechanism and barrel being capable of swinging through a larger are without interfering with the mechanical operation of the gun barrel.

4. A gun mount having a series of gun barrels mounted to swing therein, a perforated link connecting said barrels together near the forward end thereof, said gun barrels passing through openings in the link, sleeves on each of said gun barrels on each side of said link, said sleeves being clamped to the gun barrels and'against the link, a crank below said link and connected thereto by a connecting rod through which the gun barrels are oscillated in unison on the rotation of the crank.

In testimony whereof I afiix my signature in the presence of a witness.
